Abstract
A method for planting trees in an inclined face comprises the steps of providing a plurality of compartments in a sandbag made from a flexible material which the roots of tree seedlings can break through and providing each of said compartments with windows; placing a suitable soil into the compartments; and planting tree seedlings through the windows into the soil in the compartments. The sandbags containing the tree seedlings are combined into a suitable assembly, and then placed onto the inclined face with the trunks of the tree seedlings exposed through the windows. A layer of suitable soil is also provided between the sandbags and the inclined face. The assembly of sand bags containing tree seedlings is held in place while the seedlings grow by a mesh means secured by anchoring stakes. The method has the advantages of requiring minimal if any work on the inclined face, since the assembly of sand bags can be placed mechanically, for example with a crane.

.269-6 METHOD FOR PLANTING TREES ON AN INCLINED FACE
E~ACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to an improved method for planting trees in an inclined soil face, in which it is difficult to anchor seedlings.
,'. Description of the Related Art When a mountain is cut through for the purpose of, for example, quarrying or mining, an inclined face is formed on at least one side, and often both sides, of the cut. Such a steeply i;nclined face has no trees therein and, therefore, is cleficient in water-holding capacity, thus damaging the landscape and causing landslides and other disasters. It is therefore desirable to be able to plant trees in such an inclined face and green it, and to stabilise it. Sundry methods for planting trees in such an inclined face are known. An inclined face, however, that is formed after a mountain is quarried or mined normally has stones and small rocks in the soil, so that it is extremely ciLifficult to plant trees there. Nevertheless, some tree species, such as pines and other conifers will survive in such a soil of largely stones and small rocks and take root, after implantation.
For those trees to take root, however, it takes a long time, so that the planted tree seedlings have to be anchored for a long F~eriod of time in order to grow in such an inclined face.
The conventional methods include providing a layer of top soil on such an inclined face to enable the trees to grow, which inflicts, however, a quite difficult tp put in place in contrast CA 02227089 1998-01-1~
t:o flat land. Moreover, such precious top soil itself may be ~mstable may be lost, for example by rainwater erosion and other causes. Also, if the provided layer of top soil is thin, the t:rees may be lifted away from the cut face as the roots grow, so t:hat the :roots may not be implanted securely into the inclined l-ace. Moreover, if an inclined face is steep, e.g. about 70 clegrees, it is very dangerous for workers to climb up the i.nclined ~-ace and plant trees, wlth special access equlpment ls used, thus causing problems both in safety and cost.
It has been proposed to cultivate trees by planting the seedlings into sandbags. Methods of this type are described in US 5,257,476; 5,579,603; 4,299,056; 3,667,157; and 4,918,861; in C;B 2,152,345; 2,239,155; and 2,152,345 and in JP 8-246465, none of which is aimed at the dealing with planting seedlings on a steeply inclined slope.
SUMMARY OE' THE INVENTION
The present invention seeks to provide a method for planting trees fre~e from the above-mentioned problems peculiar to the prior art, and which is applicable to a steep slope or cut face.
In a first broad embodiment the present invention seeks to provide a method for planting tree seedlings which comprises:
providing a sand bag constructed of a flexible fabric through which the roots of a tree seedling are able to penet:rate;
providing a plurality of compartments in the sandbag arranged along the length direction thereof;
providing each of compartments with a window in one side of the sand bag;
providing soil suitable for tree seedlings in each of CA 02227089 1998-01-1~
the compartments, with the sandbag in a substantially hori.zontal position;
planting tree seedlings through the windows into each of the compartments;
assembling a plurality of sandbags containing seedlings into a desired sequence with the planted tree seedlings protruding on the same side;
providing further suitable soil on the inclined face to be p:Lanted;
locating the sandbag sequence on the inclined face with the t:ree seedlings exposed through the windows; and anchoring the sandbag sequence onto the inclined face by means of a staked mesh material having apertures through which the growing seedlings can pass.
Thus" the tree seedlings will grow in the sandbags using t:heir contents as a stable soil floor, and the growing tree roots will penetrate through the sandbag material and become implanted into the inclined face.
According to the planting method of the present invention, ~irst of all it is possible to supply provide the required soil and plant the tree seedlings into the sandbag laid min a substanticllly horizontal position, thus enabling the work to be clone away from the inclined face and on the substantially level qround. Second, the structure of the sandbag can be quite simple, because it: is possible to supply soil, plant trees, and expose t:he tree seedlings through the same windows. Third, the completed sandbags can be hoisted up mechanically, or lowered mechanically, with the t:ree seedlings exposed through the sandbag windows and then be (1istributed over the inclined face and fixed to complete planting, thus eliminating the necessity to arrange any CA 02227089 1998-01-1~
particula:r footholds in the inclined face and at the same time reducing the labour by the workers on the inclined face to a minimum .

DESCRIPTIC)N OF THE PREFERRED EMBODIMENTS
The preferred embodiments of the present invention will be cLescribed below with reference to the accompanying drawings.
The sandbag 1 must be made from a flexible material having such a strength that it will contain the required soil, and such that the roots of a tree seedling T can penetrate through it, as CA 02227089 1998-01-1~
t:he seedling grows. A suitable material is a non-woven fabric sheet made of polyester, nylon, polyethylene, polypropylene, and t:he like. The sandbag 1 includes a plurality of compartments 2, t:o contain soil, sequentially arranged along the direction of the :Length of the sandbag 1. Although the sandbag 1 is assumed here t:o be completely closed like a bag, it must not necessarily be completely closed but may be a bag having an opening at the end i-or examp:Le.
The sand bags include a window 3 opened into the above-mentioned compartment. Preferably, the window comprises a slit arranged along the length direction of the sandbag 1.
~lthough t.he window 3 is arranged on the basis of the number and t:he spacin.g of trees T distributed into each of the compartments
2, it also possible to provide one or more windows, thus also allowing for further subdivision of the compartment 2; the necessary compartment walls are not shown.
The i-ollowing will describe how to use the sandbag.
The ,andbag 1 is first placed substantially horizontally, i..or examp:Le, by laying on a piece of reasonably level ground.
his step need not be carried out in the location where the sandbags are to be placed. Then, by flexing the compartments 2 of t:he sandbag 1 in a direction to open the slit shaped windows 3, t.he windows 3 are deformed into a large somewhat circular shape, t.hrough which soil 4 is supplied into each of the compartments.
Subsequently, into each compartment 2 containing the soil 4, t.he tree seedlings T are planted through the windows 3. In this case, as -the tree seedlings T, it thus convenient to use trees cultivatecl by methods such as "container cultivation" or "pot CA 02227089 1998-01-1~
(ultivation". The trees cultivated in a container are pulled out with the adhering soil 5 hardened along the internal geometry of the container as attached to the roots, and then :inserted :into the sandbags used, thus realizing secure planting (see FIG. 3).
The sandbags containing the trees are then assembled into a deslred secIuence, such a linear arrangement in an extended line, which may be one or more in width. The nature of the assembly chosen is determined by the nature of the inclined face where the trees are to be located.
The completed assembly is hoisted up by a crane etc. to be arranged at a desired planting position, during which in the present embodiment the soil 1 is pulled by its own weight in a direction of its own whole length, so that the windows 3 are solidly closed as a consequence of their original slit shape, t:hus preventing the soil 3 from leaking out, and securely holding t:he seedlLngs T.
The assembly of sandbags 1 is fixed in place on the inclined f-ace G, by means of a mesh material, secured by suitable anchors.
~s shown in FIG. 5, anchors 7 are first buried driven into the inclined face G at a prescribed spacing. These anchors are made Irom a suitable material capable of being driven a suitable clistance into the inclined face. In most applications, a metal stake of up to 3 meters in length is used as the anchor 7. N~
as shown in FIG. 6, the assembly of sandbags containing both the soil 1 ancl the tree seedlings T is hoisted up with a crane etc.
and arranged in the inclined face G with the tree seedlings exposed through the windows 3 in the sandbags 1.
CA 02227089 1998-01-1~
The sandbags arranged in the inclined surface G are, as shown in FIGS. 1 and 3, pressed onto the inclined surface by means of a mesh material 6, which is fixed to the anchors 7 at lhe same ltime. The mesh material 6 must have therein apertures lhrough which the trunks of the trees T can pass. a suitable mesh material is thus wire or plastic netting; a grid-like zLssembly of wires can also be used (see FIG. 6).
Although the mesh 6 is fixed to the anchors 7 protruding from the inclined surface G with for example a wire 8, it may of course be fixed with any other suitable means, such as by engaging t:he wire 8 with rings a or hooks provided at the head of t:he anchors 7. In the latter case, installation is easier.
In the above-mentioned embodiment, soil 10 is also provided between the sandbag assembly and the inclined face G so that the t:ree seecLlings T will take root well, and also so that the assembly of sandbags 1 may be adapted to the irregularities in t:he surfaces of the inclined face G.
The tree seedlings T after planting first grow in the soil 2 in the sandbag 1. As the tree seedlings grow larger, their roots break through the sandbag 1 and grow into the soil 10, and expand toward the inclined face G. Finally, the tree roots penetrate into the inclined face G (see FIG. 7).
During the above-mentioned processes, the trunks T1 of the t:rees T expanding over the ground will of course pass through the apertures in the mesh material 6. It is desirable that as the t:rees grow-, the expanding trunk is able to split the mesh, so the trunk enlargement is not impaired. The trees T, will usually be planted initially with a density of about 8 - 10 seedlings per CA 02227089 1998-01-1~
square meter. As the trees grow larger, this will usually be reduced to a density of about 1 - 3 per square meter by natural processes. Also, the mesh material 6 will be remain fixed in place for a considerable period of time, ideally many years, until the roots of the trees T are locked together into both the soil prov:ided for their growth and the inclined face to provide a natural forest, in order to prevent the surface soil of the -Lnclined face G from belng lost.
Many tree species are suited for use in the present invention. Typical examples are Juniperus Chinensis, Juniperus Conferta, Euonymus Fortunei, Cotoneaster, Cotoneaster Horizontal, ~litex Rotundifolia, etc. The species planted will be chosen to suit the topography and climate of the inclined face.
The present invention has the following inherent merits:
(1) initial planting of the tree seedlings is carried out on substantially horizontal ground and, after that, the assembly of sandbags can be hoisted up and then arranged and Iixed in an inclined face mechanically, so that minimal planting work is necessary on the inclined face, thus enabling easy planting in any inclined faces having poor footholds.
(2) Trees can be planted easily also when the inclined f-ace comprises stones and rocks together with but small amounts c)f soil.
The i-ollowing will describe how to use the sandbag.
The ,andbag 1 is first placed substantially horizontally, i..or examp:Le, by laying on a piece of reasonably level ground.
